Just wanted to provide a heads up that I just saw this Thread and have now contacted an appropriate department to find out what's going on.

Will try to provide more information as soon as possible.

It looks like around 3:30 am PST the Login Servers began to experience an issue.

It was quickly noticed through our alert system and our On-Call Team began troubleshooting the overall issue, but unfortunately that process took quite a bit of time, and eventually required all Servers to be brought down and restarted to ensure a stable environment going forward.

I am sorry that this wasn't communicated sooner, and that it took a while to be resolved.
